The outermost broken line illustrates a display screen or portion thereof and forms no part of the claimed design. Stippling in the drawings is used to indicate a contrast in appearance, with no specific color or other feature being claimed. The remaining broken lines represent elements of the display screen or portion thereof with a transitional graphical user interface that form no part of the claimed design. The appearance of the transitional image sequentially transitions between the images shown in FIGS. 1-3 in the first embodiment, FIGS. 4-6 in the second embodiment, FIGS. 7-9 in the third embodiment, FIGS. 10-12 in the fourth embodiment, FIGS. 13-15 in the fifth embodiment, FIGS. 16-18 in the sixth embodiment, FIGS. 19-21 in the seventh embodiment, FIGS. 22-23 in the eighth embodiment, FIGS. 24-25 in the ninth embodiment, FIGS. 26-27 in the tenth embodiment, FIGS. 28-29 in the eleventh embodiment, FIGS. 30-31 in the twelfth embodiment, FIGS. 32-33 in the thirteenth embodiment, and FIGS. 34-35 in the fourteenth embodiment. The process or period in which one image transitions to another image forms no part of the claimed design. 

CLAIM We claim the ornamental design for a display screen or portion thereof with a transitional graphical user interface, as shown and described.
